Q. Hi. I need to reduce the voltage of a DC power supply from 16V (external laptop battery) down to 12V so I can use it as a power supply for my other 12 volts gadgets. Can I use an AC wall light dimmer for this? I've read that this works by reducing voltage so an incandescent lamp can be dimmed. I'd like to know your thoughts if it will work for my purpose.
A. You need to learn what regulation means. You might get it to reduce the voltage but that is NOT regulating it.
Replacing a wall light fixture?
Q. I am trying to replace a bathroom wall light fixture. My dilemma is the fixture I took out of the wall has a strip of light bulbs with 6 wires (3 white/3 black). The new fixture only has 2 wires (1 white/1 black). Which wires do I use? What do I do with the extra wires? Will the connection work without the ground?
A. Remove the extra white and black wires, they should be just jumpers connected to the main wires. Then it is white to white, black to black. The connection for a light will work without a ground, but it is safer and to code to use a ground. Usually there is a green or thin bare wire, from the fixture for the ground. It can be directly connected to the box the main wires come into.
do i paint my cabinets dark and walls light or the other way around?
Q. I want to paint my kitchen walls and cabinets but dont know if the walls should be a little darker than the cabinets or maybe the walls light and the cabinets dark. Also I have paneling I want to paint so do I paint it a different color than the walls and cabinets.
A. I'd paint the cabinets lighter and the walls a little darker shade. Nothing hardly makes a house look as old or as out of style as dark cabinets. Dark cabinets just scream 1970's and 1980's. The paneling color partly depends on where it is. You also may want to use some wood putty over the grooves in the wood paneling if it's the wide 1970's style paneling. If the panels are narrower (about 2" or so), I'd leave the grooves in place.
Don't worry about the room being too dark if you go with a slightly darker color for the walls. The walls don't have to be all that much darker than the cabinets. I'd go with a medium tone for the walls and a light tone for the cabinets.
